Zeiss Otus 28mm f/1.4 APO-Distagon

Examples: Focus Stacking

The Zeiss Otus 28mm f/1.4 APO-Distagon makes an outstanding lens for focus stacking.

The highly corrected design of the Otus 28/1.4 along with a low level of breathing (change of magnification when focusing at different distances) all making stacking unusually easy.

Tip: outer-zone peripheral forward field curvature and focus shift mean that the last frame should be shot at the most distance point and/or focused in one of the distant corners.

White Rocks to Distant Sprinter

This image gave me fits in trying go stack it because that bright hillside was hard to preserve with detail without making the rest of the frame way too dark (+100 shadows and -100 highlights not enough!). Ultimately I darkened things somewhat, retaining a satisfactory amount of detail in that hillside. Stacking with very high contrast scenes like this can be hard.
